ON THE MOUND

RHP Anibal Sanchez (6-6, 4.00) vs. RHP Jhoulys Chacin (9-9, 3.39): Winless since June 10, Sanchez in the second half is 0-4 with a 5.40 ERA and a .326 opponents' batting average in 33 1/3 innings (six starts). Five of Chacin's nine wins have come at Coors Field, where he owns a 3.27 ERA and is holding opponents to a .203 average.

Third base prospect Matt Dominguez, who suffered a hamstring injury last week, is expected to miss 10 days to two weeks. Dominguez reported feeling much better, but the Marlins likely will be cautious with him so as not to jeopardize a possible September call-up.

The injury could not come at a worse time for Dominguez, who was 12 for his last 21 (.571) with two doubles, two homers and eight RBI before he got hurt. Since returning from the Triple-A All-Star break, Dominguez is hitting .295 with a .856 on-base plus slugging, and for the season he can also boast a .313 average (25-for-80) with runners in scoring position.

Rosters can expand as early as Sept. 1, but the Zephyrs' season does not end until Sept. 5.

Asked how's expected to win with a lineup sans Hanley Ramirez, Omar Infante and Morrison, McKeon said: "It's tough, but I go to church every day. Sometimes I think I'm going to have to go twice a day. You do the best you can with what we got."
